Next week we will be focussing on subtraction. The first thing we need to know is how you do subtraction at the moment, so here are some questions for you to have a go at.
83 – 57 382 – 155 444 – 186 502 – 245 1625 – 717 3007 – 1999
Do them in your learning log and post your answers on the blog. Then watch these videos. They explain some subtraction methods which you may have used in school. What do you think? Do you have any questions?
There are many ways of doing subtraction and we have to find those that work consistently for us. You need one “go to” method that you would use for most questions because it always works. There may then be other questions that you use other methods for because it is more efficient.
